Electromagnetic induction in outer space and energy conservation

“lets pretend we are in space. and there  I have a permanent magnet rotor that and around it are copper windings. They do not touch and everything is floating with minimum friction (because we are in space)
imagine a generator with no brushes or bearings….

now my question is :
if i spin the rotor, and electrons start flowing on the copper(electricity)
would there be a negative force on the rotor to make it stop faster ?

Thank you

3.”The resistivity of a wire 1 ohm meter.”Explain.
4.What is the resistivity of(a)copper(b)nichrome?
5.What will happen if nichrome wire is used in transmission lines?
